A Look Inside Grand Seiko's 9F Quartz Movement

As a simple point of comparison, your typical run-of-the-mill quartz movement is rated to about 15 seconds a month. But the quartz crystal is just the tip of the iceberg. Performance, and how that performance is expressed visually through the dial-side of the watch, was also taken into consideration by Grand Seiko’s watchmakers and engineers.
